Gases Flashcards
Pain
universal room temperature
25°C
the force exerted by air molecules in Earth’s atmosphere against a surface. It is also known as air pressure
Atmospheric Pressure
standard surrounding pressure/atmospheric pressure.
1 atm
state of matter that features closely packed or compactly arranged atoms
Solid
state of matter that has a definite volume, but no fixed shape. It follows the shape of the container.
Liquid
state of matter that has no fixed shape or volume. Normally, it fills up the container’s volume; no shape.
Gas
In the Physical Characteristics of Gases, gasses assume the __________ of their containers.
volume and shape
In the Physical Characteristics of Gases, gases are the most _____ state of matter.
compressible
In the Physical Characteristics of Gases, gases will mix _________ when confined to the same container.
evenly and completely
In the Physical Characteristics of Gases, gases have much lower ______ than liquids and solid
densities
Law for Volume + Pressure
Boyle’s Law
Law for Volume + Temperature
Charles’ Law
Law for Temperature + Pressure
Gay Lussac’s or Amonoton’s Law
Law for Amount + Volume
Avogadro’s Law
Law for Amount (mole) + Temperature + Volume + Pressure
Ideal Gas Law
Law for Pressure
Dalton’s Law
the amount of force applied to an area
Pressure
These units are literally the difference in the heights measured in mm (h) of two connected columns of mercury.
mm Hg or torr
Higher sea level =
lower atm
= lower atm
Increasing high/altitude
As you go _____, there is an INCREASE in pressure
DEEPER
states that gas particles are in constant motion and exhibit perfectly elastic collisions.
Kinetic Molecular Theory of Gases
According to the Kinetic Molecular Theory of Gases, collisions among gas molecules are perfectly…
elastic
formula for Kinetic Energy…
KE = ½ mu^2
gas law that states that a gas’s pressure and volume are inversely proportional.
Boyle’s Law
formula of Boyle’s Law
PV = k
an experimental gas law that describes how gases tend to expand when heated.
Charle’s Law
formula of Charles Law
V/T = K
states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.”
Avogadro’s Law
formula for Avogadro’s Law
PV = nRT
states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the gases in the mixture.
Dalton’s Law of Partial Pressures
The relationship between the pressure and the temperature of a gas
Amonton’s Law
an amalgamation of the three previously known laws which are- Boyle’s law PV = K, Charles law V/T = K, and Gay-Lussac’s law P/T = K
Combined Gas Laws
the is the process by which gas under pressure escapes from one compartment of a container to another by passing through a small opening.
Gas Diffusion
